Backup NST with noogie You just need noogie, so only follow instructions from the top of the page through step 8 of the 17-step list near the bottom. Ignore all instructions for downloading and installing URamdisk (that comes later). Note: Ignore recommendation of class 6 card; card listed above works fine. Once you've burned the noogie image, if you get lost, Jocala's backup/restore page has a few tips for you.

Steps

Operate

The current state of the kernel driver that supports USB host mode is a bit unreliable.
You may need to experiment a bit to get USB host mode to work.

Important: You must be using an adapter cable that clearly says OTG.
You can find them all over the internet.
It is not important if they say that it is for a Samsung or HTC or any other brand, but it must clearly say OTG.

Due to the internal state of the driver, this works most reliably after a reboot.

Hit "Off" in the UsbMode app. This keeps your Nook from trying to charge itself from the keyboard by turning off the current.

Plug the OTG cable into the Nook.

Hit the "Host" button in the UsbMode app. The green LED light show illuminate.

You may need to hit the "Host" button several times to get your Nook properly into host mode.

Plug the keyboard into the OTG cable.

The keyboard will now be correctly working.

Correctly Removing the Keyboard

In order to correctly unmount the keyboard from the Nook, follow these steps.

Unplug both the keyboard and the OTG cable from the Nook.

In the UsbMode app, hit "Auto". This enables regular charging by turning the current back on.

In the UsbMode app, hit "Peripheral". This finishes enabling regular charging by taking the Nook out of host mode and into peripheral mode.
